Title: Toner concentration detecting method of electrophotographic copier
Inventor: AZUMA TAKAAKI
IPC: G03G15/08
Filed: 1979-01-22
Abstract: PURPOSE:To detect the concentration of toner by providing a torque detector to a magnetic brush roller or the like and detecting the change in the rotating torque of said roller or the like based on the conveying load of the developer. CONSTITUTION:A torque detecting means 5 has the two cylindrical bodies 52, 53 which are attached to the revolving shaft system of a magnetic brush roller 33, etc. and are connected by a coil spring 51. The cylindrical body 52 is fixed to the revolving shaft 33a of the magnetic brush roller 33 and is held slidably in the axial direction to the revolving shaft 61 of a motor 6. A switch operating piece 71 is provided to the cylindrical body 53 and is disposed in the position where the switch 74 corresponding to the operating piece 71 is turned ON when the cylindrical body 53 moves to the motor side. Now, when the amount of the toner decreases, the carrying load of the developer increases, resulting in the increased torque of the magnetic brush roller 33. This causes the cylindrical body 53 to move to the motor 6 side, due to which the switch 74 goes ON. As a result of this, a toner replenishment control unit operates to replenish the toner. In this way, the toner concentration may be detected.

Filed: 1991-01-23
Abstract: PURPOSE:To provide a more correct azimuth, position or running locus by making corrections with the difference between the vehicle moving direction obtained by acquiring the position data twice from the outside and the vehicle moving direction obtained based on the estimated position data. CONSTITUTION:A desired map including the present position is displayed on a display 9 from a map memory before running, the initial position of a vehicle is set on the map, the initial azimuth is set by a geomagnetism sensor 3, and they are fed to a an azimuth estimation section 5 and a position detection section 6.

Abstract: PURPOSE:To attain waveform shaping of an input signal without malfunction by connecting an MOSFET whose drain and gate are connected and operated at the saturation region and an MOSFET to which an inverting signal of an output of an inverter is inputted in parallel to obtain a hysteresis. CONSTITUTION:Since a node (a) is at 5V with an FETQ2 turned off when an input IN is 0V, an FETQ6 is turned on and an output OUT is at 0V. When the input starts increasing and it exceeds the sum of the threshold values VTH of the FETQ2, Q3, the potential at the node (a) starts descending, the FETQ6 is turned off and the output OUT is increased. Then an FETQ4 is turned on by the output OUT and the level of nodes a, b fall down to 0V. When the input IN starts descending from 5V conversely, since the FETQ2 is turned on even at the arrival at the change point at the rising, the output OUT is unchanged and when the potential descends further and is lower than the threshold value of the FETQ2, the FETQ2 starts being turned off, and when the potential at the node (a) exceeds the threshold value of the FETQ6, the FETQ2 is turned on, the output OUT goes to 0V and the change point of the falling is only the threshold value of the FETQ2.

Abstract: PURPOSE:To improve the reliability of an equipment connecting to a local area network by selecting an interface correctly. CONSTITUTION:When transmission reception of data is made directly to an Ethernet cable by using a transceiver cable 4 in compliance with a specific interface, at first a transmission reception section 13a selects a destination to be its own station and sends a packet in a form in matching with the interface. Upon the receipt of the packet by the transmission reception section 13a, a discrimination section 13b discriminates it that the transceiver cable 4 connecting to a CPU 13 is adapted. When the transmission reception section 13a does not receive the packet, the discrimination section 13b discriminates that the transceiver cable 7 connecting to a CPU 13 is not adapted. Then a changeover switch 11 throws its contact to the position of a contact 11a under the control of a changeover control section 13c. Thus, the transceiver cable 4 adapted to a printer server 5 is connected to the server 5.

IPC: G11B15/467
Filed: 1985-01-19
Abstract: PURPOSE:To speed up the phase acquisition operation of a PLL circuit after area switching by varying the phase of switching pulses when an area being reproduced is switched and correcting the rotating speed of a rotary head. CONSTITUTION:The PLL circuit 9 which generates a clock required to read an information signal recording in an area in synchronism with switching pulses for switching the rotary head. When the area is switched and the phase is unlocked from the PLL circuit 9, the output of an LPF11 increases above a specific value and a window comparator 21 detects that. At this time, a correcting means 22 generates a voltage for the number and direction of an area to which switching is performed and applies the voltage to a drum control circuit 5. Therefore, the rotating speed of the rotary head is varied and corrected forcibly. Thus, when the playback area is switched from, for example, C to D, the phase of switching pulses are varied and the rotating speed of the rotary head is corrected to stabilize the PLL circuit after the area switching speedily.
